I have slowly been raising my prices for the November sales. I don’t do free shipping on my site or Etsy. I am trying to raise my prices on Amazon to be sure to cover shipping. I hate free shipping. It can kill profits. If you can, raise prices incrementally, keep the 15%+/- discount on 5 - can raise prices even .50 or .75 a unit, see if you can up the sale to 6 w approx same discount - It all depends on what we sell - good luck
